angle sensors in the robolink joints

We have noticed, that for some people it is not clear how our angle encoders work and how to make use of it. Here are some facts about them:

1) we use incremental encoders from AMS (AS5304A), absolute encoders are not possible in the current design,

2) in order to define the ZERO position for each DOF, we use a hall sensor, beeing placed in the middle of each angular freedom,

3) that means: each robolink system has to be “initialized”, whenever the power is switched on,

4) the resolution of the encoders are:

29 (polepairs) x 160 (signals) = 4.640 signals per 360° = 0,078° for all rotationg motions of the size RL-50,

31 (polepairs) x 160 (signals) = 4.960 signals per 360° = 0,073° for all pivoting motions of the size RL-50,

62 (polepairs) x 160 (signals) = 9.920 signals per 360° = 0,036° for all motions (rot AND piv.) of the size RL-90 (Base joint),

you can find more information in our current catalogue on page 18 or in our documentation on pages 10-12 (=> pdf download in the support&service area of the robolink homepage).

 

 The FAQ list will be updated soon (it does currently not contain our new products).

robolink grippers 2 and 3 jaws

We now offer 2 different gripper versions: 2 and 3 jaws angular grippers with electrical motors. Both are running at 24 V.

First jaw version is our igus design (left side on the pictures), second version are universal grippers for the attachment of your gripper solution. Alternatively, individual gripper jaws can be designed on request. Please find attached our current data sheets. All grippers are equipped with our robolink tube d26 mm and can be adapted to our joints. The electrical cable can be guided through the arm.

robolink is still alive

dear readers, customers and friends,

robolink is not dead!

As you have certainly noticed, my blog had been paused for quite a while. I feel very sorry for that! Now it shall be working stable in the future (as my colleagues from the IT told me)!

I really hope that interested people will find back and will find interesting informations about our product robolink in the future. Today, I want to share a new igus video with some robolink impressions from 2013 (the beginning still contains scenes from 2012 that you might have seen before). Hope you can enjoy nevertheless………..thank you for your patience.

Martin
